They have real value in electronics. I don't know how much basic electricity you have taken but if you have a straight DC circuit, say a battery and a light bulb, if you have a ten volt battery and a light that will draw one amp at ten volts, that represents a ten watt bulb. You just multiply the amps times the volts and you get the power in watts.
With A ...[text shortened]... ch higher frequencies of radio and TV signals, same idea but MUCH faster cycle times.

Whose? I'm confused, and unlike anyone confused by field extensions, Wikipedia won't help me.
Or do you teach math? I had a terrible experience in HS math with an ancient teacher who refused to answer questions but only said, read the book, get the hell out of here and let me deteriorate in peace kind of thing.

I think your HS teacher had the exact wrong idea about math teaching -- if a student is taking things seriously, then they are probably asking a question for a good reason and answering their question is going to do them way more good than teaching the class does. That said, I'm going to have to remember "let me deteriorate in peace" the next time some student comes to my office hours to argue about grades or something 😛.

EDIT I agree, though. I think that with the exception of history, math is the worst-taught high school subject, on average, although my speculation about why is probably for another thread.
I've been reading your posts for a while, and we may have talked before (I used to play here as royalchicken). You have an intimidating scientific knowledge* -- what's your background?

Imagine turning on and off a laser beam 40 billion times per second, moggles the bind! And that is just the beginning, we are developing one that modulates at one TERA hertz. Them is a lodda hertz!

Did you visit my myspace site or listen here?
If you want to look on myspace, its myspace.com/donjenningsguitar
I have 4 compositions there from my first CD.
I don't have a degree, a bit late for that. I am taking a calc course, I have a couple of DVD's from 'the Teaching Company' and I wish I had this guy as a teacher back in HS, Prof Michael Starbird form the Univ. texas, Austin.
It is a great course in my opinion anyway.
Do you think the Riemann has actually been solved?
I got this book, The Riemann hypothesis by Karl Sabbagh and he talked about that mathematician who claims to have solved it ( De Branges) but I just read a piece in Wolfram's mathworld a counter example was formulated by Conrey and Li in 1998 refuting De Branges or invalidating his work. I am of course just a layman in all this but wondered if you know of any more recent work.
